Product Structure

Working Principle

Our cutting-edge permanent magnet frequency conversion air compressor is engineered with an advanced pressure sensor that instantaneously detects the actual pressure and air consumption within the system. This sophisticated setup leverages precise electric and frequency converter controls to seamlessly adjust motor speed while maintaining the constant torque of the air compressor motor. This results in an expertly regulated system pressure, allowing for the precise output of compressed air tailored to your specific demand. When the system's air consumption diminishes, the inverter air compressor intuitively decreases rotational speed, thus optimizing compressed air output. Conversely, it can increase the motor's speed to boost compressed air volume, ensuring a steady and stable system pressure is consistently maintained.

By incorporating advanced vector control technology, our unit excels with a versatile speed range, ensuring minimal motor temperature rise while delivering optimal torque to drive the air compressor smoothly and effectively. This technology intelligently segregates the motor current into torque-generating components and other vectors, allowing precise allocation of current values. Vector control technology expertly compensates for voltage drops at the motor end, enabling the motor to deliver maximum torque without surging the current, thereby enhancing efficiency and reliability.


Advantages of Permanent Magnet Variable Frequency Screw Air Compressor

Our frequency conversion regulation significantly slashes the actual power consumption of the frequency conversion compressor, directly translating energy into effective air compression. This innovative approach ensures unparalleled energy efficiency and conservation.

Cost Reducing
Experience a remarkable reduction in energy costs with our permanent magnet frequency conversion technology, cutting expenses by over 35%. Additionally, the compressor's life cycle cost sees an impressive 22% average reduction. The initial investment in this advanced compressor technology is recoverable within a swift period of 1 to 2 years, offering substantial economic benefits.

Steady Pressure
The application of the sophisticated PID (proportional, differential, integral) method ensures precise adjustments, uniquely calibrating the compressor to reliably uphold stable system pressure. This meticulous control guarantees consistent operational efficiency.

Life Extension
Our frequency conversion technology initiates operations smoothly, significantly diminishing the impact on both the power grid and machinery. This gentle start-up approach effectively extends the service life of your equipment, ensuring long-lasting, dependable performance.

Top Quality
Our commitment to excellence is reflected in the use of premium imported bearings and state-of-the-art rotor profiles. With large rotors that deliver substantial displacement at low speeds while minimizing noise, we enhance both operational efficiency and production quality, setting new industry standards.
